Abstract: 23,233. Baker, G. S. Nov. 11. Moulding, special processes for.-Relates to a machine for automatically tilling moulds or other. receptacles with plastic, liquid, or semi-liquid substances, for settling or shaking the substance down uniformly in the receptacles, and finally, when desired, cooling the substance. The substance to be treated is contained in a double-walled hopper 1, provided with stirrers 3, water being circulated between the walls by means of a pump, to keep the hopper at the desired temperature. The bottom of the hopper is provided with a preferably inclined outlet 19, Fig. 5, in communication with a reciprocating slide 20, formed with a pocket 21 and a nozzle 22. Adjacent to the hopper is a pump 26, which sucks the substance from the hopper when the pocket 21 registers with both the hopper and the pump, and discharges it through the nozzle into moulds 23, when, on the return movement of the slide, connexion between the hopper and the pump is shut off. For treating certain materials, a fixed knife 27<a>, Fig. 5, is provided to shut off the month of the nozzle. In a modification, the knife may be mounted on a rocking arm, and operated by a cam ; or it may be replaced by a fixed wire. A number of pumps and tilling-nozzles are provided, the plungers 27 of the pumps being all bolted to a cross-head 28, reciprocated, by rods 29, through a bell-crank lever 30, a rod 32, bell-crank lever 33, and cams 34 on the main shaft 11. One arm 31 of the lever 30 is slotted to receive the rod 32, the position of which may be adjusted by a screw 35 to vary the stroke of the pump and so to regulate the quantity of material discharged. The slide 20 is operated by levers 37, 38 and cams on the main shaft. For dealing with materials of stiff consistency, the pump may be replaced by or supplemented with feed-rolls placed adjacent to the hopper outlet 19. The receptacles, shown as trays 23, are carried on endless conveyer chains or belts 40, Figs. 19 and 20, intermittently driven by ratchet-wheels 43 and pawls 44, operated through spring-controlled rods 46 and bell-crank levers 45 by cams 47 on the main shaft. Screw adjustments are provided in the levers 45 to regulate the feed. An auxiliary ratchet gear, Fig. 19, is provided to move the chains sufficiently to allow for the gaps between the trays caused by the studs 41 on the conveyer chains, and so to cause the receptacles to register properly with the filling-nozzles. The chains 40 deliver the receptacles on to belts 46<b>, which convey them to a series of bands 48<b> passing over tapping-tables adapted to settle or shake the materials compactly down in the receptacles. The. bands 48<b> may rest on, or be partly enclosed in, other leather bands, to deaden the shock of the tapping-tables. All the bands and chain-wheels are mounted on adjustable pulleys and bearings, respectively. The tapping-tables 47<b> comprise one or a series of wooden or other surfaces, to which vertical and lateral vibrating or shogging motions are imparted. The tables may rest loosely on cams, or be mounted on fixed transverse or longitudinal springs 51, for instance of lance-wood, which are acted on by the cams 52. The receptacles, after leaving the tapping-tables, may be transferred to other belts and carried to cooling- chambers, if desired. Glazed chambers or boxes 55 are provided to protect the materials from dust during their passage from the hopper to the cooling-cbamber. A number of machines may be placed together, having their hoppers connected in series and provided with circulation water by means of one pump.
